About the Lord, nice!
It's hard to make out what you've done with the GS on the detailing, so I'll reserve judgment until it's painting time for you, but it looks rather fancy form what I can see.
The pose for the Juggernaut though , that is clearly going to be made of awesome and win when it's done. What colour scheme have you proposed for the beast? I personally reckon that something other than the classic red and bronze would go down a treat. How about a colour scheme like your Terminators, red and black with bone trim? That'll be striking as you like.
Also, got anything good planned for the base? Some sharp rocky outcrops could work, or perhaps something more daemonic?
I'll stop gibbering now and let you get on with it. Looking forward to whatever you come up with
